| pubmed-article:10451428 | pubmed:abstractText | Spinal motor neurons possess reticular coats of extracellular matrix proteoglycans on their somata and proximal dendrites. In order to define the anatomical background of the network, spatial relationships of the perineuronal proteoglycans with synaptic boutons and astrocyte processes were analyzed in rat motor neurons by TEM after histochemical detection of the substances with cationic iron colloid, and by SEM after exposure of the cytoarchitecture with NaOH maceration. Narrow intercellular channels filled with proteoglycan were found to extend along the surface of the neurons to form a homogeneous network of a mesh size of about 1 microm. The system of perineuronal channels consisted of two parts: a primary intervaricose net which meandered among synaptic boutons on the surface of the motor neuron, and secondary subvaricose nets which irrigated interfaces between larger boutons and the neuron. No elements in the perineuronal cytoarchitecture coincided with the meshwork of proteoglycan, indicating the involvement of postsynaptic factors in the distribution of the substance. Thin astrocyte processes surrounding the neurons formed a distinct network with heterogeneous meshes corresponding to boutons of various sizes. The perineuronal glial nets extended their surface area in contact with the intervaricose nets of proteoglycan by complex cellular interdigitations. The subvaricose nets of proteoglycan compartmentalized multiple synapses on large boutons, suggesting an involvement in the division of the synapses during development. | lld:pubmed |
